Basically I had set up FB on my phone with my other emails. I also enabled Facebook chat on it as well. However, I got a message from someone both on the Facebook app as well as on the "Messaging/Online Threads" section. The thing is that I don't have texting from my calling number anymore and it looks like it only got sent to my profile's message inbox on FB and on the Messaging Online Threads.

Am I going to be charged or I can still send a message Since before replying it says "Chat on Facebook"??? Thanks
